FBI finds hundreds of weapons at home of suspected shooter of Arizona Democratic Party office.

Jeffrey Michael Kelly , 60 , was arrested on Tuesday night near his Ahwatukee Foothills home.

Authorities also found BB guns and rifles consistent with what they said were fired at the Democratic campaign office in Tempe , Arizona .

The latest incident occurred on Oct. 9 around 12:30 a.m. at the office near Southern Avenue and Priest Drive , north of the Arizona Mills Mall.

The previous two shootings occurred on Monday, Sept. 16 , and Sept. 23 , at the same location.

Arizona Democrats shuttered the field office two days after the third shooting.

Police saw that the same silver sports utility vehicle was used in each shooting.

A prosecutor out of the Phoenix City Attorney’s Office declined to pursue charges, Weich said. The Republic has reached out to Phoenix police and the city’s attorney. Weich said he fears that Kelly managing to evade law enforcement may have pushed him to act further, leading to an escalation on Tuesday . "We saw that he obviously felt emboldened," Weich said. Further details were expected to come later Wednesday afternoon . (This story was updated with new information.)
